  • Robust typescript support 💪

  • Implement with vue 3 reactivity system only

via npm

yarn add vuex-light

via cdn

<script src="https://unpkg.com/[email protected]"></script>

Getting Started

Create the simplest store:

// store.ts
import { createStore } from 'vuex-light'

// Create a new store instance.
export const store = createStore({
  state: {
    count: 0,
  mutations: {
    increment({ state }) {

Now, your can access the store by the following ways:

  1. globalProperty

    // main.ts
    // Adds the $store property that can be accessed in any component instance inside the application.
    app.config.globalProperties.$store = store
    app.component('child-component', {
      mounted() {

    Example: Hello world

  2. provide/inject

    // main.ts
    import { createApp } from 'vue'
    import { store } from './store'
    const app = createApp({
      inject: ['store'],
      template: `
          {{ store.state.count }}
    // Sets the store that can be injected into all components within the application.
    app.provide('store', store)

    Example: Counter

  3. useStore

    // store.ts
    // create the `useStore` composition function
    export function useStore() {
      return store
    // in a vue component
    import { defineComponent } from 'vue'
    import { useStore } from './store'
    export default defineComponent({
      setup() {
        const { state, mutations } = useStore()
        return {

    Example: Todo MVC

Core API

const store = createStore({
  state: {
    count: 0,
  getters: {
    isOdd({ state, getters }) {
      // ...
  mutations: {
    increment({ state, getters, mutations }, ...payloads) {
      // ...
  actions: {
    incrementIfOdd({ state, getters, mutations, actions }, ...payloads) {
      // ...
